Embodiment Construction

[0017] As will be discussed in greater detail herein, versions of an ultra-wideband (UWB) system and method provide a local area network (LAN) and / or LAN access. LAN access versions of the UWB system includes an emulator layer and bridge that allow data to be transmitted between a LAN-UWB hybrid device and a LAN network switch, such as an IEEE 802 network switch, through in part a UWB node of a UWB WPAN that can receive UWB super-frames from the LAN-UWB hybrid device. In some implementations the LAN-UWB hybrid device uses WiFi protocol layers above the emulator layer and a WiNet Peer IP PAL layer below the emulator layer.

[0018] LAN versions of the UWB system can direct data communication between two LAN-UWB hybrid devices each within the same UWB WPAN of the same UWB node or separate WPANs of the different UWB nodes. LAN (WiFi for some implementations) packets are generated by one or both of the LAN-UWB hybrid devices and are sent between each other through a network switch, such a...

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention is directed generally to data network communication. [0003] 2. Description of the Related Art [0004] Wi-Fi is used to identify a technology directed to wireless local area networks (WLAN) based on the IEEE 802.11 specifications (including 802.11, 802.11a, 802.11b, 802.11g). The technology can be used for mobile computing devices, such as laptops, in LANs, and other device connectivity. Both the 802.11 family of networking protocols and the 802.3 family of networking protocols involves an area of networking sometimes referred to as infrastructure networking that is related to networking other than peer-to-peer networking. [0005] 802.11 has a maximum bandwidth of 2 Mbps, which can be too small for many applications. 802.11b supports bandwidth up to 11 Mbps, which is comparable to traditional IEEE 802.3 and other Ethernet versions. 802.11a supports bandwidth up to 54 Mbps and signals in a regulate...
